BACKGROUND OF INVENTION

1. Field of Invention

The present invention is directed to a novel Internet scanning terminaland a novel method for surfing Internet World Wide Web (WWW) using barcode symbols encoded with the Uniform Resource Locators (URLs)indicating the location of Web-Sites within the WWW to be explored.

2. Background of the Invention

Presently, several techniques have been developed for connecting to(i.e., “surfing” among) Internet Web-sites using a conventionalgraphical user interface (GUI) based Internet browser programs, such asthe Navigator® from Netscape Communications, Inc. or the InternetExplorer® from Microsoft, Inc. Notably the availability of anyparticular Web-site surfing technique depends, of course, on where theInternet user finds him or her self in the Internet browser program atany particular instant of time.

For example, if one is currently at a Web-site (i.e., in a particularHyperText Markup Language (HTML) document), at which there is ahighlighted “link” or embedded URL specifying the Internet address ofanother Web-site (i.e., another HTML document), then the user can “surfto” this other Web-site by simply “clicking on” or selecting thehighlighted URL with his or her pointing device (i.e., “mouse”) in aconventional manner. The ability to connect to other Web-sites by simplypointing and clicking on a highlighted URLs embedded in an HTML documenthas contributed enormously to the growth and popularity of the Internetin the last few years.

If the user desires to connect to a Web-site that is not referenced in aHTML document viewed through a browser program, then the user oftentimesfind it necessary to manually enter the URL of the Web-site (e.g.,“http://www.metrologic.com”) into the browser program. This requiresmanually pressing a sequence of keys on a keyboard or remote controldevice, corresponding to the characters of the URL being selected. Inaddition to being time consuming, this Web-site surfing technique isprone to errors, causing the browser program to connect to the wrongWeb-site or return a message stating that the Domain Name of theWeb-site sought after cannot be found. From practical point of view,this is quite frustrating to the Internet user.

More recently, with the growth and ever increasing complexity of theWWW, it is becoming popular to use printed publications (e.g. magazines,catalogues, directories, etc.) which list Web-site, corresponding URLsand content descriptions, as navigational aids, much in same way thatthe TV GUIDE® magazine is used to help viewers select programs duringtelevision viewing. Again, however, each time a listed Web-site is to beviewed, the user is forced to manually enter into the Internet browserprogram, the lengthy character string associated with the URL of theWeb-site being selected. Only thereafter, does the browser programautomatically connect the user's client system (i.e., Internet Terminal)to the Internet information serving computer supporting the selectedWeb-site.

While the development of HTML and GUI-based Web browser programs havemade accessing Web-sites quite simple, the above shortcomings anddrawbacks of prior art Internet technology clearly indicate a great needin the art for an improved system and method of surfing to Web-sites onthe Internet.

DETAILED DESCRIPTION OF THE ILLUSTRATIVE EMBODIMENTS OF THE PRESENTINVENTION

The illustrative embodiments of the present invention will be describedwith reference to the figure drawings wherein like elements andstructures are indicated by like reference numbers.

In general, the system and method of the present invention is practicedin connection with a globally-based digital telecommunications network(known as the Internet). The function of the Internet is to provide aninfrastructure that supports wired and wireless digitaltelecommunications throughout the world using the well known TCP/IPnetworking protocols. In general, the Internet infrastructure comprisesInternet Service Providers (ISPs), Network Service Providers (NSPs),routers, telecommunication lines and channels, etc., all well known inthe art.

Connected to the Internet 1 by way of the Internet infrastructure (i.e.,ISPs and NSPs) are many Internet Web-site Servers (i.e., computersystems) 2 that are physically located throughout the world and whosefunction is to serve information to Internet users when requested byclient computer systems (i.e., client systems) 3. In general, eachInternet Web-site Server 2 and client system 3 may be connected to theinfrastructure by way of an ISP 4 (or NSP) using physical communicationmedia or a wireless (RF-based) digital communication link 5 well knownin the art. Notably, while each illustrative embodiment of the InternetScanning System hereof is realized in the form of a Client Systemoperably connected to the infrastructure of the Internet by way of anISP, it is understood that the Internet connection may be achievedthrough an NSP or access point in the Internet infrastructure.

In the illustrative embodiments, each Internet Web-site Server 2 isrealized as a computer system running conventional Web-site serversoftware (e.g., WebStar® from StarNine, Inc.) and is interfaced with anISP in a conventional manner. Each Internet Web-site Server is assigneda unique IP address (and Domain Name) on the Internet, and is providedwith Internet networking software to support the TCP/IP protocol. Inaddition, each Internet Web-site server is provided with one or moreapplication software programs for creating and maintaining hypermediadocuments containing text, graphics and audio information within aninformation file structure expressed in HTML. Each HTML document on theWWW is physically stored in an Internet Server 2. The location of suchinformation storage on the WWW is specified by a Uniform ResourceLocator (URL), the syntax of which is well known in the art The functionof a URL is best illustrated by way of example. Metrologic Instruments,Inc., the assignee of the present invention, has launched a WWW sitehaving a “home page” (i.e., first page) specified by the following URL:“http://www.metrologic.com”. The type of information maintained at thisWeb-site, beginning with Metrologic's home page, can be virtually anytype of information (of a multi-media nature) and typically will beupdated over time to reflect changes in either the company, itsproducts, services and the like. The same is generally true for each andevery other Web-site on the Internet, regardless of the type ofinformation being served to client systems.

As illustrated in FIG. 1, the first illustrative embodiment of theInternet Scanning System hereof is realized in the form of a desktopcomputer system 6. As shown, the desktop computer system consisting of avideo monitor 6A, a processor 6B, keyboard 6C and mouse 6C, is connectedto the Internet by way of an ISP 4. The computer system 6 has aGUI-based web browser program and a hand-held, wireless laser scanningbar code symbol reading system 7 which is connected to the communicationport of this host system in a conventional manner. In the preferredembodiment, wireless bar code symbol reading system 7 comprises ahand-supportable laser scanning bar code symbol reading device 7A and abase unit 7B which receives RF signals transmitted from device 7A uponthe successful reading of each bar code symbol thereby; the base unit 7Bproduces an acoustical acknowledgement signal in response to each suchsuccessful read. System 7 can be realized by any one of the (i) wirelessbar code symbol reading systems disclosed in copending application Ser.No. 08/292,237 filed Aug. 17, 1994, or (ii) tethered bar code symbolreading systems disclosed in copending application Ser. Nos. 08/476,069and 08/660,643, each said copending application being incorporatedherein by reference. The function of the programmed bar code symbolreader 7 is to read a bar code symbol 8 that is encoded with the URL ofa Web-site to be accessed by the Internet Scanning System, and producesymbol character data representative of the URL. As used hereinafter,this special type of bar code symbol shall be referred to as a“URL-Encoded Bar Code Symbol”. The information structure of this symbolcharacter string should be formatted so that it corresponds to thesyntactical structure of the URL and is thus readily utilizable by anyconventional GUI-based Internet browser program, such as the Navigator®from Netscape or the Internet Explorer® from Microsoft. When this URLinformation is provided to the Internet browser program, the particularWeb-site corresponding to the URL is automatically accessed by theInternet Scanning System.

In general, each URL-encoded bar code symbol of the present inventioncan be either a linear (1-D) or 2-D bar code symbol structure ofvirtually any symbology that allows for the encoding of the ASCH-typeinformation contained within a URL-type information structure, thesyntax of which is well known in the art. In the preferred embodiment,the URL-Encoded Bar Code Symbol 8 is realized as a truncated-type barcode symbol of Code 128 or Code 39 Symbology. Preferably, each such barcode symbol is printed above, below or alongside each Web-site URL 14 orits listing in a Web-site guide or directory. In general, theURL-encoded bar code symbol can be of any length. Notably, the advantageof using the truncated bar code symbol structure is that the height ofthe bars and spaces is relatively short in relation to the length of thebar code, thus allowing the URL-encoded truncated Symbol 8 to be easilyprinted with each Web-site listing printed on crowded pages of printedWeb-site guides and catalogues, as illustrated in FIG. 1A.

In accordance with the present invention, Web-site listings in whichURL-encoded bar code symbols may be printed, include various types ofprinted guides, directories or publications which digest, catalogue,organize or otherwise list WWW sites that exist on Web-site Serversthroughout the Internet. Examples of such printed Web-site publicationsinclude, for example: the “WWW Yellow Pages” (1996) published by the NewRiders Publishers, Inc.; “PC NOVICE GUIDE TO THE WEB: How to findanything on the Web” (1996) published by Peed Corporation;“Cybersurfer”, published by Starlog Group, Inc.; “Internet Underground”,published by Ziff-Davis; “Internet User”, published by Ziff-Davis;“Internet World”, published by Mecklermedia; “The Net”, published byImagine Publishing; “Net Guide”, published by CMP Media; “OnlineAccess”, published by Red Flash Internet; “The Web”, published byInternational Data Group; “Websight”, published by New Media, Inc.;“Yahoo Internet Life”, published by Ziff-Davis and Yahoo; WebTV Guides;or any other printed publication that one may desire to use to look upWeb-sites (of interest) that one would like to visit (surf to) andexplore.

As shown in FIGS. 1 and 1A, the programmed bar code symbol scanner 7 ofthe Internet Scanning System of the first illustrative embodiment isparticularly designed so that closely nested Web-site listings on asingle page can be read without inadvertently reading undesiredURL-encoded bar code symbols. This added scanning control feature isachieved in the bar code symbol reader of FIG. 1 by providing theautomatic laser scanning bar code symbol reader 7A with anoptically-transparent scanning plate 9A supported from reader 7A by anoptically transparent extension 9B. The scanning plate 9A has formedtherein a sighting window (i.e., aperture) 10, through which aURL-encoded bar code symbol 8 is automatically scanned and read whensuch a printed symbol (on a substrate) is aligned with the sightingaperture. In this particular embodiment of the bar code symbol reader7A, the IR-based object detection field 11 extends just slightly beyondthe sighting window 10 so that the laser scanning by laser beam 12 sautomatically initiated only when an object (e.g., Web-site Guide) 13 isplaced up against the sighting window 10, as when the scanning plate isbrought in contact with URL-Encoded Bar Code Symbol 8 associated with aparticular Web-site listing, shown in FIG. 1A. The design andconstruction details associated with automatic bar code symbol reader 7Acan be found in Applicant's prior U.S. application Ser. No. 08/1292,237filed Aug. 17, 1994, incorporated herein by reference. As shown in FIG.1, this scanning device can be provided with a keypad 15 in a mannerknown in the art, for manually entering the characters of URLs, neededor required.

As shown in FIG. 2, the second illustrative embodiment of the InternetScanning System hereof is realized in the form of an interactiveweb-based television system 16 which comprises an Internet Terminal Unit17, a Remote Control Scanning Device 18 and a standard (NTSC or PAL)color television set 19. As shown, the Internet Terminal Unit 17 isconnected to the Internet by way of an ISP 4 and includes means forsupporting: (i) a GUI-based Internet browser program such as theInternet Navigator® from Netscape Communications or the InternetExplorer® from Microsoft, Inc.; and (ii) the TCP/IP networking protocolon the Internet. In the preferred embodiment, the Internet Terminal Unit17 can be realized using any one of a number of commercially availableInternet Terminal devices, such as, for example: the Mediamaster 9500™Internet Terminal from Nokia, Inc.; the NetStation™ Internet Terminalfrom Acorn Computer; or the “Internet Digital Appliance” from Diba

As shown in FIG. 2, the Remote Control Scanning Device 18 of the secondillustrative embodiment can be realized by integrating a miniatureautomatic bar code symbol reading module 20 into the wireless remotecontrol device that is provided with the commercially available terminalunit that is used to practice this embodiment of the present invention.Preferably, automatic bar code symbol reading module 20 is similar tothe device described in great detail in Applicant's copendingapplication Ser. No. 08/292,237 supra. Such laser scanning engines, asthey are called, are commercially available from Metrologic Instruments,Inc., of Blackwood, N.J., under the tradename ScanQuest®. The manner inwhich such a laser scanning engine can be integrated into any one of theremote control devices of the above-identified Internet Terminals, andthus provide the Remote Control Scanning Device 18, will be describedbelow.

The Mediamaster 9500™ Internet Terminal from Nokia, Inc., theNetStation™ Internet Terminal from Acorn Computer, or the InternetDigital Appliance from Diba, are each provided with a wireless remotecontrol device which includes a programmable microcontroller (i.e.,microprocessor) operably connected to a system bus of one sort oranother. The system subcomponents that are connected to the system busstructure include, for example: program memory realized in the form ofEPROM 21; data storage memory realized in the form of RAM 22; a keypad23, data storage registers and interface circuitry; an IR-basedcommunication circuit and interface circuitry 24; and a power supply andpower distribution circuitry 25. In such commercial products, no visualdisplay device (e.g. LCD panel) is provided, as all display functionsare provided on the television screen using an on-screen display formatwell known in the art. Integration of an automatic ScanQuest™ LaserScanning Module (Model No. IS4120) into the system architecture of suchwireless remote control devices can be achieved by adding additionaldata registers to the system bus, and connecting the data output port ofthe scanner to such registers in a conventional manner. Additionalcontrol logic will have to be provided by the microcontroller in toprovide scan data from the scanner priority over data entered manuallyinto the system. All such modifications are within the ordinary skill inthe art.

As shown in FIG. 2, Remote Control Scanning Device 18 has anoptically-transparent scanning plate 9A supported by an opticallytransparent extension 9B. The scanning plate 9A has formed therein asighting window (i.e., aperture) 10, through which a URL-encoded barcode symbol 8 is automatically scanned and read when such a printedsymbol (on a substrate) is aligned with the sighting aperture. TheIR-based object detection field 11 extends just slightly beyond thesighting window 10 so that the laser scanning beam 12 is automaticallyinitiated only when an object (e.g., Web Guide) 13 is placed up againstthe sighting window 10, as when the scanning plate 10 is brought incontact with URL-Encoded Bar Code Symbol 8 associated with a particularWeb-site listing, shown in FIG. 2. During operation, the Remote ControlScanning Device 18 is used to read URL-encoded bar code symbols 8printed on Web-site GuideBook 13 in order to connect to thecorresponding Web-sites thereof.

While any standard (NTSC or PAL) color television set can be used inconnection with the Internet Terminal 17 to display graphical and audioinformation content associated with any particular Website accessed bythe system, it is preferred that a higher-resolution (VGA or SVGA)computer monitor is used in connection therewith to display highresolution graphics.

As shown in FIG. 3, the third illustrative embodiment of the InternetScanning System hereof is realized in the form of a hand-held ScanningIntegrated Terminal. The Scanner Integrated Terminal 26 is shownconnected to an ISP 4 by way of a radio-base station 27 and wirelesslink 5. The hand-held Scanning Integrated Terminal 26 has an integratedGUI-based World Wide Web (WWW) browser program, display panel 28,touch-screen type keypad 29, and programmed bar code symbol scanner 20.The function of the bar code symbol scanner 20 is to read a bar codesymbol 8 that is encoded with the URL of a Web-site to be accessed bythe Internet Scanning System, and produce symbol character datarepresentative thereof.

In the illustrative embodiment, the Scanner Integrated Terminal 26 isrealized as a transportable computer, such as the Newton® Model 130MessagePad 30 from Apple Computer, Inc. of Cupertino, Calif. This deviceis provided with NetHopper™ brand Internet Access Software from AllPenSoftware, Inc., of Los Gatos, Calif., which supports the TCP/IPnetworking protocol within the Newton MessagePad. The Newton MessagePadis also equipped with a Motorola PCMICA-based modem card 31 having a RFtransceiver for establishing a wireless digital communication link witheither (i) a cellular base station, or (ii) one or more satellite-basestations (27) connected to the Internet by way of an ISP 4 in a mannerwell known in the global information networking art. While it isunderstood that, in some instances, it may be desired to connect a penor wand device to the serial port of the Newton MessagePad to providebar code symbol reading capabilities thereto, it is generally preferredthat automatic laser scanning engine 20 (e.g., Metrologic ScanQuest®Laser Scanning Module Model No. IS4120), be interfaced with the serialcommunications port of the Newton MessagePad so as to realize theInternet Scanning System of the third illustrative embodiment hereof.

As shown in FIG. 3, the entire Newton MessagePad, ScanQuest® LaserScanning Module 20 and auxiliary battery supply (not shown) arecompletely housed within a rubberized shockproof housing 32, in order toprovide a hand-supportable unitary device. The rubberized housing isprovided with an scanning aperture 10 realized within an opticallytransparent scanning plate 9B supported by extension 9A. The function ofthe scanning aperture 10 is to allow the projected laser beam 12 tosweep across a URL-encoded bar code symbol 8 located within the sightingwindow 10 of optically-transparent scanning plate 9B, once the object(e.g., Web-site guide) 13 is detected by the object detection field 11.

In each of the three illustrative embodiments described above, the barcode symbol scanner can be replaced by a programmed optical characterreader realized using the automatic holographic laser scanningtechnology disclosed in great detail in Applicant's copendingapplication Ser. No. 08/08/1573,949 filed Dec. 18, 1995, incorporatedherein by reference. The function of the programmed optical characterreader is to allow the Internet Scanning Terminal to access any desiredWeb-site by reading the alphanumeric character string comprising the URLthereof, and provide the same as output to the GUI-based Internetbrowser program thereof. In such alternative embodiments, the functionof the optical character reader (i.e., character reading module) is toread the SCII characters comprising the URL 14 printed on a web-siteguide or like publication, avoiding the need for manual key entryoperations.

The Internet Scanning Terminals of the present invention may bemodified, in a variety of ways, to carry diverse range of bar codesymbol scanning functions.
